The uv4l people have update their code and you can now stream real-time high resolution video to a browser. And it works on the Raspberry Pi. The ‘u’ in uv4l is for ‘user’. It is a user-space wrapper around the low-level kernel driver v4l. It is just a matter of time before the people making v4l put the finishing touches on it and it will come standard on linux distributions. On the Raspberry Pi, work is underway on v4l2.
